Then I remove the pen/dowell and bullet,re-install the bolt,close it,then I replace the cleaning rod in the rifle and lower it until it touches the bolt face,then mark that point on the rod flush with the muzzle.
I then measure these 2 points that I have marked,and it gives me the measurment (COL) of the ORIGIN of the rifling for that bullet profile.I can then subtract the desired amount of bullet gap that I wish,or how far into the lands that I desire.
I don't buy into the need for fancy equipment,this has always worked for me,before this I used the 'smoke it and see' method,it takes way too long!
